I and useful Dustand Cinder Trap, of which Be it known that I, CHARnEsI; LENIG, a citizen of the United States, residing at Danville, in the county of Montour and State of Pennsyl-vanimhave invented a new the following is a specification.

This invention relates to a dust and cinder trap adapted to be attached tothe-side of a railway car, or other swiftly moving vehicle.

The object of the invention is to providea device of this kind which may be attached so as to extend between the windows on the side of a car, or other vehicle, in such a manner that the dust and cinders are trapped and conducted to the end of the car, so that they are prevented from entering the windows when the latter are open. Provision is also made for reversing the action of the air currents through the device, so as to adapt the same for the movement of the car in either direction. The attachment is so arranged that the cinders and dust, which would otherwise have a tendency to enter the windows when the latter are open, will be deflected to one side thereof without interfering with the ventilationof the car or obstructing the View from" the windows.

The principles of the invention and the details of the construction, by means of which it is carried out, will be more clearly described in connection with the accompanying drawings, which illustrate the pie ferred form thereof.

In the drawings:

Figure 1 is'a side e'levationof aportio-n of a railway car having the invention installed thereon.

Figure 2 is a plan view of the invention.

Figure 3 is an enlarged. perspective view of a portion of the trap, showing the relation of the conduits and gutters thereto.

Figure 4 is a horizontal sectional view through the trap.

Figure 5 is a view similar to Figure 4, but with the damper in a different position.

Figure 6 is a view, partly in elevation and partly in section, of the upper end of the trap.

Figure 7 is a vertical transverse section on the line 7-7 of Figure 4.

Figure 8 is a sectional view of the lower end of the trap, taken on the line 8-8 of Figure 7.

The invention, as shown, is attached to inwardly extending the side of a railway car 10, and consists of-a series of traps 11 disposed vertically between the windowsof the car and connected at the top and bottom by conduits 12, which extend to 'th'e end of the car where they may be connected by apipe 13 leadin'g'toa' convenient point near the ground, Where the cinders and-dust collected by: the traps may be discharged, without causingany annoyanoe' to the passengers.

7 Each of the'traps-comprises a flat side 14" adapted to rest against the side of the'car, and having at the top and bottom substantially semi-cylindrical bands 15 and 16, respeotively, which are held in spaced relation by vertical spaced strips 17 and 18. The bands15 and 16" are extendedover the ends of the trap toform caps 19 and- 20. Secured tothe inner facesof these caps are flanges 21' and 22 concentric with the bands-15 and 16 and spaced therefrom to form' guidewa-ys' 23 and 24, which slidably' receive the ends of the curved damper 25. The latter is in the shape of a cylindrical segment extending through an arc of approximately 120, so that, as shown inFigures 3, 4 and'5, it may be adjusted to close one side of the trap while the otlier'side; is left open. A suitable wing or vane 26 may be secured centrally of the outer surface of the damper 25 and is moved betweenthe upright strips 17 and 18 for the purpose of adjusting thedamper.

Each-of the conduits 12, above referred to, which connect the" upper and lower ends" respectively ofthe traps 11, includes a tubu-" lar section27 and a gutterseotion 28'. The corners of the damper are cut away, asshown at 29, so that the'ends of the tubular sections are always open, while the ends of the gutter sections may be selectively closed by the damper together with the adj acent side of the trap. The tubular sections 27 serve to conduct thecinders or dust received through the open side of the trap, while the gutter serves to conduct the dust which enters through the longitudinal opening 30, between the edge of the gutter and, the tubular section, into the tra In Figures 3 and 4 the damper is turned to the left, this being the proper position for. trapping the oinders and dust when the vehicle is moving toward the right. In this position the cinders and dust entering through the longitudinal opening 30, be-

tween the tubular portion 27and side of the gutter 28, pass along the gutter into the trap 11, while the opening 31 in the front side of thetrap serves to trap all cinders passing the sides of the windows. "The cinders which are thus trapped will be conducted through the tubular sections 27 and the successive traps until they reach the down wardly, extending discharge portion 13 of the conduit, whence they will be discharged near the ground and out of the way. The eddies set up by the open sides of the traps 11 and the open sides of the gutters 28 will be suiiicient to cause the deflection of cinders and dust particles from the air, and the size tions markno material departure from the scope of the invention as claimed.

hat is claimed is: r

1. An attachment for railway cars and the like, comprising a trap having top and bottom caps spaced apart and provided with transverse curved guideways, a damper extending from top to bottom of the trap and slidable in said guideways to open either side of the trap while closing the other side, and a. conduit leading from the trap for conducting the intercepted par ticles to the end of the car. is v V r 2. An attachment for railway cars and the like, comprising a plurality ottraps adapted to be attached between the. side windows of the car, each trap having top and bottom caps and provided with transverse curved guideways, a curved damper extending from top to bottom of the trap and operable to open either side of the trap wnile closing the other side, conduits connecting the traps to each other and leading curved I the conduits and opening into the respective traps, said damper being extended so as to open and close the ends of the respective gutters, and being cut away so as to leave the ends of the conduits always open.

3. The combination with a vehicle having side windows, of a series of dust and cinder traps adjacent the sides of the windows, each of said traps being hollow and substantially semi-circular in. cross section, conduits connecting the traps and leading to the ends of the car, and slidable means for closing either side of the trap and at the same time opening the other side.

i. The combination with a vehicle having side windows, of a series of dust and cinder traps, one being adjacent the side of each window, said traps being hollow and substantially semi-circular in cross section, conduits connecting the traps and leading to the ends of the car, open gutters adjacent the conduits between the traps and opening into the interior of the traps, and a slidable damper for each trap operable to close either side of the same while at the same time opening the other side.

5. The combination with a vehicle having side windows, of a series of dust and cinder traps adjacent the sides of the windows, each of said traps being hollow and substantially semi-circular in cross section, conduits conn'ecting the traps to each other In testimony that I claim the foregoing I at the top and bottom respectively and leading to the cut away sufiiciently toleave the conas my own, I have hereto atiixedmy signature.
